Abstract
Abstract A surgical deflector or boring tool positioner specifically designed to help orthopedic surgeons in gaining access to hard-to-reach parts of a patient's anatomy and for guiding a drill bit, awl or reamer into a bone. The tool combines a curved blade and a triangular handle. The curved blade is terminated by an arcuate indentation designed to seat on a bone. The triangular handle doubles as a muscle deflector. One of a series of boring guides can be mounted on the blade to direct the tip of the boring tool into the bone at a desired angle. A fiberoptics light may be clipped to the shank of the tool to illuminate the work area.
